The Korean Collagen Skin Booster Global Doctors Are Paying Attention To
Hello, I am Dr. Oh Seung-min, director of O.N Clinic. The presentation I gave at the IMCAS conference in Paris on liquid PCL Gouri received a lot of attention. It is very encouraging that a product developed with Korea's unique technology was introduced at IMCAS, the world's largest aesthetic conference, and that Medical Team from various countries showed deep interest. In particular, it was meaningful to be able to provide clear answers to the dilemmas that Medical Team faced when using existing collagen boosters, such as "Why is it so complex and variable?" and "Why are these things so difficult to solve?"
Today, based on the discussions I had with doctors from around the world at IMCAS, I would like to explain in detail the five checklists that patients should definitely check when choosing a collagen booster.
1. Formulation
As the collagen booster market grows, various products are being released. Each product has completely different manufacturing methods and philosophies. Some products are released in powder form and must undergo a process of mixing with liquid and dissolving just before use. On the other hand, some products are manufactured in liquid form from the beginning.
Why is this difference important? Products completed in liquid form from the manufacturing stage have much better uniformity in their molecular structure. You can think of it as the difference between a precisely manufactured part from a factory and a part hastily assembled on-site. Gouri is a product designed to be 100% liquid, which means it does not require a hydration process, resulting in fewer variables during the procedure and the advantage of expecting consistent results.
2. Nodules & Clumping
One of the biggest concerns patients have after a collagen booster procedure is the phenomenon of nodules, where the treated area feels unnatural or can be felt by touch. Traditional collagen boosters, due to their particle-like nature, tended to remain strongly in the injected spot. This required massage to spread them evenly, or precise techniques during the hydration process. Ultimately, this means that additional intervention not solved by the product alone was necessary.
"Traditional collagen boosters, due to their particle-like nature, tended to remain strongly in the injected spot. As a result, massage was required, or very precise techniques were needed for things like hydration to ensure even spreading."
In contrast, the liquid collagen booster Gouri, developed with the latest technology, creates a uniform distribution without artificial intervention. The reduction in the need for special care after the procedure is a really big advantage for busy modern people.
3. Lifting Effect & Mechanism
What is the difference between existing collagen boosters and Gouri? Both are ultimately collagen boosters. The mechanism of action, which induces collagen synthesis by injecting them into the skin or subcutaneous tissue, is similar. However, Gouri has one more characteristic: it is liquid from the start. Because it is injected as a liquid, there is no clumping, and it stimulates collagen synthesis uniformly. From a Lifting perspective, it can spread stably to deep layers, creating structural support. This is the biggest differentiating factor.
4. Procedure Efficiency & Predictability
Even with the same product, the consistency of results can vary depending on how standardized the procedure process is. This is an area that patients may not be familiar with, but it is actually very important. Traditional collagen boosters tend to have a complex preparation process before the procedure. They must undergo a dissolving process for a certain period under appropriate conditions, and variables can arise during this process depending on the practitioner's skill level.
On the other hand, Gouri, which is completed in liquid form from the beginning, has a greatly simplified preparation process. Because it comes ready to use, the consistency and predictability of the procedure are much higher. Ultimately, patients can receive shorter procedure times, a smoother injection sensation, and more predictable results. Consult via chat now
5. Scientific Basis & Global Validation
No matter how theoretically excellent a technology may seem, it is difficult to trust if it is not supported by sufficient clinical experience and scientific data. This was the point I emphasized most at IMCAS. Being presented and discussed at a world-leading aesthetic conference like IMCAS means that Medical Team from various countries have actually used and validated it. In particular, the recognition of technology developed in Korea in the European market is proof of its excellent technical completeness, as medical device regulations in Europe are very strict.
Although liquid collagen booster technology was developed in Korea, its safety and effectiveness are already recognized at a global level. It is a verified technology that has undergone intense discussions and upgrades with doctors from various countries. I strongly felt at IMCAS Paris that K-beauty is creating synergistic effects simultaneously with K-culture and K-music, and is becoming a trend rather than just a passing fad. I hope this trend continues to grow well.
In summary, when choosing a collagen booster, you should not only look at the name or a single ingredient, but also consider the following:
- Formulation
- Stability
- Convenience
- Efficacy
- Scientific Basis
However, no matter how good a product is, the results may vary from person to person depending on who performs the procedure. O.N Clinic is a clinic where the director personally provides Consultation, creates customized packages, and performs procedures according to principles. I believe that if you accurately remember these five checklists I mentioned today, you will be able to make a much safer and wiser choice.
If you have any questions about skin procedures, please leave a comment. We will guide you to the most suitable Lifting, using the most scientific method. Thank you.
